Abstract: A plurality of warp threads includes total N adjacent tightening threads each repeats crossing over N second legs at a side of the first tape-surface and crossing over the weft thread at a side of the second tape-surface so as to tighten the coil-shaped element to the weft thread. Said N indicates a natural number equal to or greater than 2. Each tightening thread includes an exposed portion that crosses over the weft thread and is exposed at a side of the second tape-surface. As the N adjacent tightening threads extend, the respective exposed portions of the tightening threads appear at a side of the second tape-surface one-by-one alternately or one-by-one sequentially.

Abstract: An incorporated slide fastener that is incorporated simultaneously with the weaving of the fastener tape for a zigzag-type continuous element. The weft yarn of the fastener tape is woven with one thread traversing and doubling back in the tape width direction, forming a set of two threads. Fastener elements have: engaging heads; first and second leg portions that each extend in the width direction of the tape; first connecting portions that connect first legs that are adjacent in the longitudinal direction of the tape; and second connecting parts that connect second legs that are adjacent in the longitudinal direction of the tape. Of the two yarns configuring the weft yarn, one yarn is woven diagonally straddling the first surface of a first leg and the second surface of a second leg of adjacent fastener elements.

Abstract: A detecting system of a fastening apparatus that detects an axial force of the fastening apparatus including a bolt or a nut. The detecting system includes an axial force detector including a strain gauge and an IC tag, the strain gauge being provided at a predetermined location to detect an axial force value of the fastening apparatus, and the IC tag being connected to the strain gauge and wirelessly transmitting the detected axial force value and unique identification information. Power is supplied to the axial force detector. A reader reads data transmitted from the axial force detector.

Abstract: An ion source device is capable of reducing deterioration of a source due to virulent gas, such as moisture or oxygen, which may adversely affect an ion source, while maintaining the ion source in an ion source driving installation state. An ion source device, which is installed for operation, is supplied with gas, such as inactive gas, which contains a reduced level of gas with possible adverse effect on the ion source, through an ion source driving gas supplying line form the outside of the device, such as a man-made satellite equipped with an ion source. Moreover, inactive gas remaining in a storage vessel provided in the course of the inactive gas supplying line, discharges on itself, thereby continuously purging the ion source.

Abstract: A woven slide fastener in which displacements of element anchoring warps in a width direction of a fastener tape does not occur, flexibility of the fastener and smooth operation of a slider are ensured, and anchoring of a fastener element row is stable. Two anchoring warps disposed closest to coupling heads out of a plurality of element anchoring warps running over upper leg portions of the fastener element row run with and parallel to a double-picked foundation weft running under lower leg portions of adjacent elements and are woven in a width direction of a fastener tape body portion while interlacing with other element anchoring warps and foundation warps. Therefore, the element row can be anchored firmly, and the two anchoring warps do not fall off the elements, and other element anchoring warps also do not fall off of the elements.
